Low Power LCD

Hi everyone.

I need a low power LCD module. What's the lowest current consumption you guys have ever seen?
I have one right here that says its max current consumption is 1mA at 5V.
Is there anything lower? A micro amp LCD?
I don't have any voltage restriction right now.
What's the LCD choice when you are running on a small battery?

Hope someone can help me.
Best Regards,
Fernando

Fernando,

Our lowest power consumption module we have is our subcompact CFAX12864AP1-NFH. This module is optimized to run at 3v, and has no backlight - the rated specs are 1mA and is often less draw than that.

Please let us know if you have any questions.

can you suggest a charecter lcd module for optimized to run at 3v. thank you.

None of the standard character modules are "optimized" to run at 3v.

They can be used at 3v, but you need to meet the Vlcd spec, which will typically mean driving Vo (pin 3) below ground.

Connecting LCD to Low voltage PIC

What about the spec for "supply voltage for logic" being greater than 4.5volts? Will this work correctly with a 3volt supply?

I am working with a CFAH1602B-TMC and trying to connect to a low voltage PIC.

What is the simplest way to create a negative voltage for Vo? (assuming the LCD has NO built in negative voltage generator)

Thanks,
